<h4 class="subsubsection">9.8.4.4 Assembler Directives</h4>
<a name="index-assembler-directives_002c-CRIS"></a>
<a name="index-pseudo_002dops_002c-CRIS"></a>
<a name="index-CRIS-assembler-directives"></a>
<a name="index-CRIS-pseudo_002dops"></a>

<p>There are a few CRIS-specific pseudo-directives in addition to
the generic ones.  See <a href="Pseudo-Ops.html#Pseudo-Ops">Pseudo Ops</a>.  Constants emitted by
pseudo-directives are in little-endian order for CRIS.  There is
no support for floating-point-specific directives for CRIS.
</p>
<dl compact="compact">
<dt><code>.dword EXPRESSIONS</code></dt>
<dd><a name="index-assembler-directive-_002edword_002c-CRIS"></a>
<a name="index-pseudo_002dop-_002edword_002c-CRIS"></a>
<a name="index-CRIS-assembler-directive-_002edword"></a>
<a name="index-CRIS-pseudo_002dop-_002edword"></a>

<p>The <code>.dword</code> directive is a synonym for <code>.int</code>,
expecting zero or more EXPRESSIONS, separated by commas.  For
each expression, a 32-bit little-endian constant is emitted.
</p>
</dd>
<dt><code>.syntax ARGUMENT</code></dt>
<dd><a name="index-assembler-directive-_002esyntax_002c-CRIS"></a>
<a name="index-pseudo_002dop-_002esyntax_002c-CRIS"></a>
<a name="index-CRIS-assembler-directive-_002esyntax"></a>
<a name="index-CRIS-pseudo_002dop-_002esyntax"></a>
<p>The <code>.syntax</code> directive takes as <var>ARGUMENT</var> one of the
following case-sensitive choices.
</p>
<dl compact="compact">
<dt><code>no_register_prefix</code></dt>
<dd>
<p>The <code>.syntax no_register_prefix</code> <a name="crisnous"></a>directive
makes a &lsquo;<samp>$</samp>&rsquo; character prefix on all registers optional.  It
overrides a previous setting, including the corresponding effect
of the option <samp>--no-underscore</samp>.  If this directive is
used when ordinary symbols do not have a &lsquo;<samp>_</samp>&rsquo; character
prefix, care must be taken to avoid ambiguities whether an
operand is a register or a symbol; using symbols with names the
same as general or special registers then invoke undefined
behavior.
</p>
</dd>
<dt><code>register_prefix</code></dt>
<dd>
<p>This directive makes a &lsquo;<samp>$</samp>&rsquo; character prefix on all
registers mandatory.  It overrides a previous setting, including
the corresponding effect of the option <samp>--underscore</samp>.
</p>
</dd>
<dt><code>leading_underscore</code></dt>
<dd>
<p>This is an assertion directive, emitting an error if the
<samp>--no-underscore</samp> option is in effect.
</p>
</dd>
<dt><code>no_leading_underscore</code></dt>
<dd>
<p>This is the opposite of the <code>.syntax leading_underscore</code>
directive and emits an error if the option <samp>--underscore</samp>
is in effect.
</p></dd>
</dl>

</dd>
<dt><code>.arch ARGUMENT</code></dt>
<dd><a name="index-assembler-directive-_002earch_002c-CRIS"></a>
<a name="index-pseudo_002dop-_002earch_002c-CRIS"></a>
<a name="index-CRIS-assembler-directive-_002earch"></a>
<a name="index-CRIS-pseudo_002dop-_002earch"></a>
<p>This is an assertion directive, giving an error if the specified
<var>ARGUMENT</var> is not the same as the specified or default value
for the <samp>--march=<var>architecture</var></samp> option
(see <a href="CRIS_002dOpts.html#march_002doption">march-option</a>).
